Plan Mode in Continue – Safe, Read-Only Code Exploration

Learn how to use Plan Mode in Continue to explore and understand codebases safely with read-only tools, search, and analysis before making changes

What is Plan mode?

Plan mode is a restricted environment that provides read-only access to your codebase. It’s designed for safe exploration, understanding code, and planning changes without making any modifications.

What Are the Key Features of Plan Mode?

• Read-only tools: Access files, search, and analyze without risk
• Safe exploration: Perfect for understanding unfamiliar codebases
• Planning focus: Develop implementation strategies before execution
• MCP support: Works with all MCP tools alongside built-in read-only tools

How Plan Mode Works

Plan mode filters the available tools to only include read-only operations. This means you can:

• Read any file in your project
• Search through code with grep and glob patterns
• View repository structure and diffs
• Fetch web content for additional context
• Use all MCP tools

But you cannot:

• Create, edit, or delete files
• Run terminal commands
• Make any system changes

What Is the Common Workflow for Plan Mode?

1. Start in Plan mode to explore and understand
2. Develop your approach with the model’s help
3. Switch to Agent mode when ready to implement

What Tools Are Available in Plan Mode (Read-Only)

In Plan mode, only these read-only tools are available:

• Read file (read_file)
• Read currently open file (read_currently_open_file)
• List directory (ls)
• Glob search (glob_search)
• Grep search (grep_search)
• Fetch URL content (fetch_url_content)
• View diff (view_diff)
